What it detects

This rule detects the loading of AzureCommunication.dll from outside the Windows directory, a masquerading module name used by the Project CAV3RN espionage framework that abuses Outlook calendar events and Graph API for command-and-control. A cloud-themed module name loaded from an unexpected path is indicative of an attacker blending malicious code into legitimate-looking Azure components.
